Pet emissions

Oxfam’s Duncan Green (a cat person) reports these BBC numbers tongue-in-cheek (sort of…):

Using a unit known as a ‘global hectare’ – a measure of the land area needed to support a certain ecological footprint, growing and manufacturing the 164kg of meat and 95kg of cereals a border collie or cocker spaniel eats every year takes about 0.84 gha. A bigger dog such as a German shepherd consumes even more – its carbon pawprint is more like 1.1 gha. That is more than the environmental footprint of the average Indian person, who uses just 0.8 gha of resources. If you are a multiple dog owner you are in even more trouble. Two big dogs are responsible for more carbon emissions than some British citizens.

By contrast a cat (hah!) needs 0.15 gha, a hamster 0.014 gha, and a canary 0.007 gha. The most carbon efficient pet is a goldfish. Its carbon finprint requires just 0.00034 gha. That’s over 3,000 fish per pooch.

This is the first I’ve heard of the “global hectare” used thus, but it strikes me as a very sensible metric for standardizing the environmental footprint of economies or people (or animals for that matter). .
